Understanding the Early Years (UEY) is a national initiative that provides research information to help strengthen the capacity of communities to make informed decisions about the best policies and most appropriate programs to offer Canadian families with young children. This report focuses on the results of the community mapping study, conducted during the Summer and Fall of 2000. Three data sources were used in conducting the Community Mapping Study: (1) 1996 Census; (2) Neighbourhood Observations; and (3) Program Survey. The report provides an analysis of data sources to be used in Southwestern Newfoundland to gain a better understanding of: (1) Physical and socio-economic characteristics of the neighbourhoods in which children live; (2) Kinds of programs and services that were available to children aged six and younger and their parents; (3) Where these programs were located; and (4) If these programs were being used. The Mapping Study, along with the Community Study and the Early Development Instrument will provide a framework for (1) Measuring children's early development before they enter school; (2) Showing how community influences impact on child development in the early years; (3) Profiling the type and availability of community resources for families and children; (4) Assessing how well the needs of local families and young children are being met; and (5) Learning more about how research can be used at the local level to bring about improvements for children. Three appendixes are included: (1) Development of the Social Index; (2) Results of Neighbourhood Observations; and (3) Design and Results of the Community Programs Survey.
